Okay. Who HASN'T had a 12V battery issue with their 2023-24 Prime?

Yes, the true solution is to figure out why the batteries are dying in the first place. However, that still doesn't address the laundry list of user "don'ts" that Gokhan outlined. The only way to attempt to cover all those is to ensure the 12V system stays topped off whenever the car is plugged in (again, whether or not the traction battery is actively charging).

As for why they didn't choose to design around this problem, I suspect they figured it wouldn't bite them. Someone has chosen poorly....

 

they're sellingmore than they can make. so obviously...

 

SIGH...I know. The bean counters win again.

 

Most of the things on that list, ex. "leave lights off", are things for any car. The people having issues seem to have to made sure that wasn't the case.
The warning about the drain on the 12V while plugged in, where is it in the manual? It has been quoted here, but I didn't see it in the after charging section. They do warn not to leave it plugged in for a long time to avoid dirt, dust, and water building up around the plug. If the 12V going flat in such a time was a problem, shouldn't it be mentioned there?

 

Is this from the wiring diagram, or what? So if it is fully drivable why not just take the fuse out? What aux items are turned off? They said in the bulletin there is a way to recalibrate the intelligent sonar by driving. I would like to learn that if it is in the service manual.
Plus how to test the 12 volt battery sensor on the neg terminal.
Would be good info for the site.
